As shown in FIGS. 1 and 2, the elastic portion 13 is formed into a plurality of folded accordion shapes, and elastically deforms between the clamp portion 12 and the fitting bottom portion 17 so as to be extensible and contractible. When a load is applied, the elastic portion 13 is deformed to a bent state in the elastic deformation, and when no load is applied, an elastic force which is a restoring force is generated. The elastic portion 13 elastically deforms when the clamp portion 12 is pressed to the fitting bottom 17 side, and returns when the pressure of the clamp portion 12 is released. Here, the shape of the elastic portion 13 may be a bellows shape or a figure of eight.

In addition, by bending the inside of the bent portion of the elastic portion 13 formed in an accordion shape into a substantially circular shape, a wound portion 25 is formed. Here, the bent portion 25 is formed at the bent portion of the elastic portion 13, the connection portion between the elastic portion 13 and the fitting bottom portion 17, and the connection portion between the elastic portion 13 and the clamp portion 12. By forming the bent portion 25, when the elastic portion 13 expands and contracts in the axial direction, the stress acting on the bent portion can be reduced. Therefore, it is suppressed that the whitening phenomenon generate | occur | produces in the bending part of the elastic part 13, and it is suppressed that the said part degrades by extension.

As shown in FIG. 2, the fitting bottom 17 is attached to the rear end of the elastic portion 13. The fitting bottom portion 17 is a member that closes and fixes the second opening 11B of the main body 11 when the string fastener 10 is assembled. The fitting bottom portion 17 is a substantially elliptic cylindrical member, and on the outer periphery thereof, contact surfaces 18A and 18B are formed from the front side to the rear side. The contact surfaces 18A and 18B are formed to restrict the rotational movement of the fitting bottom 17 in the main body 11.

As shown in FIG. 3, the contact surfaces 18A and 18B are flat surfaces formed in a rectangular shape. As shown in FIG. 4, the contact surfaces 18A and 18B are formed at positions facing each other so as to be parallel to each other. As shown in FIG. 4, the fitting bottom portion 17 is formed into a substantially elliptic cylinder whose left and right sides are cut off by forming the contact surfaces 18A and 18B.

In the manufacturing process of the string fastener 10, referring to FIG. 1, the temporary fixing portion 14A is broken, and the clamp portion 12 is inserted into the inside of the main body portion 11. At this time, by forming the temporary fixing portion 14A in such a shape, the temporary fixing portion 14A is divided at the connection portion between the temporary fixing portion 14A and the clamp portion 12 so that the temporary fixing portion 14A remains on the main body 11 side. become. Accordingly, since the temporary fixing portion 14A does not remain on the clamp portion 12 side, the temporary fixing portion 14A protruding from the temporary fixing portion 14A does not get caught on clothes or scratch the user's finger. Such a shape is the same as for the other temporary fixing portions 14B, 14C, 14D.

With reference to FIGS. 1 and 2, the left and right side surfaces of clamp 12 and fitting bottom 17 are partially recessed inward so that they are retracted for retracting tacking portion 14A and the like during assembly described later. Grooves 26A and the like are formed. Here, retraction grooves 26A, 26B, 26C, 26D are formed corresponding to the temporary fixing portions 14A, 14B, 14C, 14D. In FIG. 1, a recess 26A is formed by recessing the left side surface of the clamp 12 and the fitting bottom 17 in a portion corresponding to the rear region of the temporary fixing portion 14A. By forming the retraction groove 26A, even when the temporary fixing portion 14A remains on the main body 11 side at the time of assembly, when the clamp portion 12 and the fitting bottom 17 are inserted into the main body 11, the temporary fixing portion 14A is It passes through the evacuation groove 26A. Thus, the temporary fixing portion 14A is prevented from contacting the clamp portion 12 and the fitting bottom portion 17.

Similarly, a withdrawal groove 26B is formed on the side surface of the clamp portion 12 and the fitting bottom portion 17 at a position corresponding to the rear side of the temporary fixing portion 14B. Further, although not shown here, retraction grooves 26C, 26D are formed corresponding to the rear sides of the temporary fixing portions 14C, 14D formed on the right side of the string fastener 10.

Furthermore, referring to FIG. 2, a plurality of engaging protrusions 27 protruding forward are formed on the rear side surface of the second insertion hole 23 of the clamp portion 12. The engagement protrusion 27 has a function of preventing movement of the string-like member 24 by biting into the string-like member 24 when the string-like member 24 is inserted into the second insertion hole 23 under use conditions. . In particular, in the present embodiment, the elastic portion 13 that exerts the elastic force to fasten the cord is made of resin, so the elastic force obtained is limited, but the engagement protrusion 27 bites into the cord-like member 24 in this manner. The effect of the cord fastener 10 for fastening the cord-like member 24 can be made sufficiently large.

A process of manufacturing by assembling the cord fastener 10 and a process of sandwiching the cord-like member 24 in the manufactured cord retainer will be described based on FIGS. 5 and 6. FIG. 5 is a side view and a cross-sectional view showing the process of assembling the cord fastener 10. FIG. 6 is a side view and a cross-sectional view showing the process of passing the string-like member 24 through the assembled string fastener 10. As shown in FIG. 5 and 6 show a state of the inside of the main body portion 11 by a broken line and show a state of cutting off a part of the main body portion 11 in order to show the state of the inside of the main body portion 11.

First, with reference to FIG. 5, the process of assembling the string fastener 10 will be described.

As shown in FIG. 5A, the string fastener 10 is prepared, and the clamp 12 is pushed into the main body 11 side. The temporary fixing portions 14A and 14B break when the clamp portion 12 is pressed toward the main body portion 11 with a predetermined force or more. When the temporary fixing portions 14A and 14B break, the clamp portion 12 is detached from the main body portion 11. With the clamp 12 removed from the main body 11, the clamp 12 is further pushed.

As shown in FIG. 3, the clamp portion 12 is pushed in a state in which the contact surface 15 </ b> A is in contact with a guide surface 21 </ b> A formed on the inner peripheral surface of the main body 11. The clamp portion 12 is pushed in a state where the contact surface 15B is in contact with the guide surface 21B formed on the inner peripheral surface of the main body portion 11. Thereby, the clamp part 12 is pushed without rotating in the main body part 11.

Further, as shown in FIG. 5B, in the present embodiment, since the retraction grooves 26A and 26B are formed on the side surfaces of the clamp portion 12 and the fitting bottom portion 17, the clamp portion to be inserted into the main body portion 11 It is suppressed that 12 and the fitting bottom part 17 contact temporary stop part 14A, 14B.

As shown in FIG. 3, the width dimension 18W between the abutment surface 18A and the abutment surface 18B is narrower than the width dimension 21W between the guide surface 21A and the guide surface 21B. The maximum width dimension 19SW of the fitting bottom portion 17 obtained by combining the width dimension 18W of the fitting bottom portion 17 and the thickness dimensions of the two engaging male portions 19A and 19B is greater than the width dimension 21W between the guiding surface 21A and the guiding surface 21B. Too wide.

For this reason, as shown in FIG. 5C, even when trying to push the fitting bottom 17 into the main body 11, the engaging male portions 19A and 19B (see FIG. 3) are the ends on the rear side of the main body 11. It will be in the state where it abuts on the part. Then, the front side of the fitting bottom 17 closes the second opening 11B. Further, in this state, the fitting bottom portion 17 is forcibly pushed into the main body portion 11 and forcibly fitted. Since the engaging male portions 19A and 19B are formed in a tapered shape in which the thickness is tapered from the rear to the front, the fitting bottom 17 can be force-fit to the main body 11 with a relatively weak force.

As shown in FIG. 3, the fitting bottom portion 17 is pushed in such a state that the contact surfaces 18A and 18B are in contact with the guide surfaces 21A and 21B formed on the inner peripheral surface of the main body 11. That is, the fitting bottom portion 17 is pushed without rotating in the main body portion 11. When the fitting bottom portion 17 is pushed into the main body portion 11, as shown in FIG. 5D, the engaging male portions 19A and 19B engage with the engaging female portions 22A and 22B. The engaging male portions 19A, 19B are formed on the contact surfaces 18A, 18B that are in contact with the guide surfaces 21A, 21B, so that they can be easily engaged with the engaging female portions 22A, 22B.

That is, the engaging male portions 19A, 19B can be engaged without rotating the fitting bottom portion 17 in the main body portion 11 and adjusting to the position engaging with the engaging female portions 22A, 22B. As shown in FIG. 2, the engaging male portion 19A is firmly engaged because the width dimension 19W and the height dimension 19H thereof are substantially the same as the width dimension 22W and the height dimension 22H of the engaging female portion 22A. The engagement male portions 19A and 19B are formed in a tapered shape having a thick rear side, and thus firmly engage with the engagement female portions 22A and 22B.

That is, even if the clamp portion 12 is pushed to the fitting bottom 17 side, the fitting bottom 17 does not come off the main body 11. As shown in FIG. 5D, when the engaging male portions 19A and 19B engage with the engaging female portions 22A and 22B and are assembled as the string fastener 10, the rear end of the main body portion 11 is , And on the same plane as the rear end of the fitting bottom 17. The fitting bottom portion 17 is engaged with the main body portion 11 in a state in which the second opening portion 11B of the main body portion 11 is closed.

Next, with reference to FIG. 6, the process of letting the string-like member 24 pass through the assembled string fastener 10 will be described. When the string fastener 10 is not inserted into the string-like member 24, it is in the state shown in FIG. 6 (A). The fitting bottom 17 closes and fixes the second opening 11B (see FIG. 1) at the rear end of the main body 11. The elastic portion 13 is located in the main body portion 11, and the clamp portion 12 has a front end portion protruding from the first opening 11A (see FIG. 1) of the main body portion 11. The first insertion holes 20A of the main body 11 are in a state in which the positions of the second insertion holes 23 of the clamp 12 do not match.

In order to insert the string-like member 24 into the string fastener 10, the state shown in FIG. First, the clamp portion 12 is pressed to the rear side of the main body portion 11 against the elastic force of the elastic portion 13. That is, the clamp portion 12 is pressed toward the fitting bottom portion 17 which is fixed by closing the second opening portion 11B of the main body portion 11. The clamp portion 12 is pressed so that the centers of the first insertion hole 20A and the second insertion hole 23 coincide or substantially coincide. In that state, as shown in FIG. 6C, the string-like member 24 is inserted into and penetrated through the first insertion hole 20A and the second insertion hole 23.

When the force pressing the clamp portion 12 is released, as shown in FIG. 6D, the clamp portion 12 moves forward by the elastic force of the elastic portion 13. That is, by the elastic force, the string-like member 24 can be fixed, that is, held by the first insertion holes 20A of the main body 11 and the second insertion holes 23 of the clamp 12. In order to move the string fastener 10 to a desired position of the string-like member 24, the clamp 12 is moved in the direction of pushing the main body 11.

When the centers of the first insertion hole 20A and the second insertion hole 23 coincide or substantially coincide with each other, the main body portion 11 and the clamp portion 12 can move with respect to the string-like member 24 so that they move to a desired position. . When pressing against the clamp portion 12 is stopped, the elastic force of the elastic portion 13 causes the clamp portion 12 to move in the opposite direction. The cord-like member 24 can be fixed, that is, held by the first insertion hole 20A of the main body 11 and the second insertion hole 23 of the clamp 12 in a sandwiching manner.

Here, as described with reference to FIG. 2, an engagement protrusion 27 is formed on the rear side surface of the second insertion hole 23. Therefore, the engagement protrusion 27 engages with the string-like member 24 by the elastic force of the elastic portion 13. Since the cord fastener 10 of this embodiment fastens the cord by the elastic force of the elastic portion 13 made of synthetic resin, it is also considered that the engaging force is small as compared with a general one using a metal spring. In the present embodiment, the engagement protrusion 27 is engaged with the string-like member 24 in this manner to prevent the string fastener 10 from moving from the string-like member 24 under use conditions.

Second Embodiment
The string fastener 50 according to the second embodiment will be described with reference to the drawings after FIG. 7. The basic configuration of the string fastener 50 is the same as that of the above-described string fastener 10, and therefore redundant descriptions will be omitted below. The strap 50 does not have the fitting bottom 17 of the strap 10. Further, in the string fastener 50, the elastically deformable side wall of the clamp portion 52 constitutes an elastic portion 53. Therefore, since the configuration of the elastic portion 53 is particularly simple, the string fastener 50 can be reduced in overall size, and by adopting such a string fastener 50 for clothes, it can be worn.

Further, as shown in FIG. 10, the guide surfaces 58A and 58B are formed at positions facing each other so as to be parallel to each other. As shown in FIG. 10, the main body portion 51 has a substantially rectangular shape in which the first opening 51A and the second opening 51B are arcs whose upper and lower sides are symmetrical due to the formation of the guide surfaces 58A and 58B. Is formed.

As shown in FIG. 9, in the main body portion 51, first insertion holes 56A, 56B are formed in a portion near the second opening 51B. The first insertion holes 56 </ b> A and 56 </ b> B are circular holes for inserting the string-like member 61. The first insertion hole 56A is formed to penetrate the cylindrical side wall of the main body 51 and the guide surface 58A. The first insertion hole 56B is formed to penetrate the cylindrical side wall of the main body 51 and the guide surface 58A.

As shown in FIG. 7, the clamp portion 52 is attached to the second opening 51 </ b> B of the main body 51 by the temporary fixing portion 55. The clamp portion 52 is a member that clamps the cord-like member 61 together with the main body 51 when assembled as the cord fastener 50.

As shown in FIG. 9, on the outer periphery in the left-right direction of the clamp portion 52, contact surfaces 59A, 59B are formed from the front side to the rear side. The contact surfaces 59A and 59B restrict the rotational movement of the clamp 52 in the main body 51.

As shown in FIG. 7, the clamp portion 52 is provided with a second insertion hole 57. The second insertion hole 57 is a hole for inserting the string-like member 61.

As shown in FIG. 8, the elastic portion 53 is a wall-shaped member formed in the rear portion of the clamp portion 52. The elastic portion 53 is a member that generates an elastic force for sandwiching the string-like member 61 when the string fastener 50 is assembled as the string fastener 50.

As shown in FIG. 8, in the present embodiment, the elastic portion 53 is a wall-shaped portion formed as a side wall of the clamp portion 52. The elastic portion 53 has an inclined shape that spreads rearward.

The pressing portion 54 is a portion pressed forward by a finger in order to operate the string fastener 50 in a use situation where the string fastener 50 is used. The sizes of the pressing portion 54 in the vertical and horizontal directions are larger than the sizes of the internal space of the main body 51 in the vertical and horizontal directions. Therefore, even if the clamp 52 is pushed toward the main body 51, the pressing part 54 is not inserted into the main body 51. The large area of the pressing portion 54 can reduce the load acting on the user's finger. In the present embodiment, the pressing portion 54 does not need to pass through the inside of the main body portion 51 at the time of assembly, so the pressing portion 54 can be formed larger than the main body portion 51.

Referring to FIG. 7, a clamp portion 60 connecting elastic portions 53 is formed at an intermediate portion in the front-rear direction of clamp portion 52. When the clamp portion 52 is pushed into the main body portion 51, the clamp portion 60 is positioned forward of the rear end portion of the first insertion hole 56A. As will be described later, the string-like member 61 comes to be held by the first insertion holes 56A, 56B and the clamp portion 60. In addition, when the clamp portion 52 is inserted into the main body portion 51, the elastic portion 53 may be deformed inwardly, and the clamp portion 60 may also be deformed forward. By doing this, it is possible to increase the elastic force that pushes the clamp portion 52 rearward, and to increase the effect of fastening the string-like member 61. In the present embodiment, the second insertion hole 57 through which the string-like member 61 is inserted under the condition of use is formed in the clamp portion 52. The second insertion hole 57 includes the pressing portion 54, the elastic portion 53 and the clamp. It is formed as a space surrounded by the part 60.

Referring to FIG. 10, in order to prevent movement of clamp 52 within main body 51, a projection is made by partially projecting contact surfaces 59A, 59B of clamp 52 outward. 62A, 62B are formed. Further, concave grooves 63A, 63B are formed by recessing the guide surfaces 58A, 58B of the main body 51 in the form of grooves. Then, when the clamp 52 is inserted into the main body 51, the protrusions 62A and 62B of the clamp 52 abut the concave grooves 63A and 63B of the main body 51. By this, it is suppressed that the position of the clamp part 52 in the inside of the main-body part 51 shifts | deviates.

As shown in FIGS. 7 and 10, the temporary fixing portion 55 is a member that temporarily holds the main body portion 51 and the clamp portion 52 by the time the string fastener 50 is assembled. As shown in FIG. 7, the temporary fixing portion 55 is attached between the inner peripheral surface of the rear end of the main body portion 51 and the outer peripheral surface of the front end of the clamp portion 52. As shown in FIG. 10, the temporary fixing portions 55A, 55B, 55C, 55D are provided between the main body 51 and the clamp 52 at the upper right end, the lower right end, the upper left end, the lower It is attached to the left end one by one. Thus, by temporarily fixing the clamp portion 52 and the main body portion 51 via the four temporary fixing portions 55 disposed corresponding to the respective corner portions of the clamp portion 52, the connection between the both is further stabilized. It can be done.

The temporary fixing portion 55A is formed in a substantially rectangular shape having a predetermined size, which is easy to be broken, so as to be easily released from the main body portion 51 and the clamp portion 52. Specifically, the area of the portion where the temporary fixing portion 55A connects with the main body portion 51 is larger than the cross-sectional area of the portion where the temporary fixing portion 55A connects with the clamp portion 52. In the manufacturing process of the string fastener 50, referring to FIG. 7, the temporary fixing portion 55A is broken, and the clamp portion 52 is inserted into the inside of the main body portion 51. At this time, by forming the temporary fixing portion 55A in such a shape, the temporary fixing portion 55A is divided at the connection portion between the temporary fixing portion 55A and the clamp portion 52, and the temporary fixing portion 55A remains on the main body 51 side. become. The matter which concerns is the same also regarding other temporary fixing parts 55B, 55C, 55D (refer FIG. 10).

The process of assembling the cord fastener 50 and the process of sandwiching the cord-like member 61 in the assembled cord fastener will be described based on FIG. FIG. 11 is a front view and an external view showing a step of assembling the string fastener 50 and a step of inserting the string-like member 61 into the string fastener 50. As shown in FIG. FIG. 11 shows the internal state of the main body 51 by a broken line and shows a state in which a part of the main body 51 is cut.

First, with reference to FIG. 11 (A) and FIG. 11 (B), the process of assembling the string fastener 50 will be described.

As shown in FIG. 11A, the string fastener 50 is prepared, and the clamp 52 is pushed into the main body 51 side. The temporary fixing portions 55A and 55B shown in FIG. 8 break when the clamp portion 52 is pressed toward the main body portion 51 with a predetermined force or more. When the temporary fixing portions 55A and 55B are detached from the main body portion 51, the clamp portion 52 is detached from the main body portion 51. With the clamp 52 removed from the main body 51, the clamp 52 is further pushed.

The clamp portion 52 is pushed in a state where the contact surfaces 59A and 59B shown in FIG. 9 are in contact with the guide surfaces 58A and 58B formed on the inner peripheral surface of the main body 51. Thereby, the clamp part 52 is pushed without rotating in the main body part 51.

As shown in FIG. 8, the width 52 W of the front end of the clamp 52 is shorter than the width 51 W of the internal space of the main body 51. Further, the width 54W of the pressing portion 54 formed at the rear end of the clamp portion 52 is longer than 51W. Further, the width 53W of the elastic portion 53 formed in the middle portion in the front-rear direction of the clamp portion 52 is shorter than 51W near its front end and longer than 51W near its rear end.

Therefore, as shown in FIG. 11B, when the clamp portion 52 is pushed into the main body portion 51, the elastic portion 53 of the clamp portion 52 elastically deforms inward, and the front portion of the clamp portion 52 It is stored. Further, the pressing portion 54 formed at the rear end portion of the clamp portion 52 is not inserted into the main body portion 51, and is exposed to the outside on the rear side of the main body portion 51. At this time, the first insertion holes 56A of the main body portion 51 and the second insertion holes 57 of the clamp portion 52 overlap each other as viewed in the left-right direction. In addition, the elastic portion 53 of the clamp portion 52 is elastically deformed inward and abuts against the inner wall of the main body portion 51 to generate an elastic force for moving the clamp portion 52 rearward.

Next, with reference to FIG.11 (C) and FIG.11 (D), the process of letting the string-like member 61 pass through the string fastener 50 assembled as mentioned above is demonstrated.

In order to insert the string-like member 61 into the string fastener 50, the state shown in FIG. First, the user presses the pressing portion 54 forward against the elastic force of the elastic portion 53, thereby inserting the front side of the clamp portion 52 into the main body 51. Then, the first insertion hole 56A of the main body 51 and the second insertion hole 57 of the clamp 52 overlap. In that state, as shown in FIG. 11C, the string-like member 61 is inserted into and penetrated through the first insertion hole 56A and the second insertion hole 57.

When the force pressing the clamp portion 52 is released, as shown in FIG. 11D, the clamp portion 52 is moved rearward by the elastic force of the elastic portion 53. Specifically, the elastic force of the elastic portion 53 which tries to return the deformation toward the outside acts in a backward direction by the elastic portion 53 coming into contact with the inner surface of the main body portion 51 and sliding. Become. With this elastic force, the string-like member 61 can be fixed or held by the first insertion hole 56A of the main body 51 and the second insertion hole 57 of the clamp 52 in a sandwiching manner.

When moving the string fastener 50 to a desired position of the string-like member 61, the clamp portion 52 is moved in the direction of pushing the main body portion 51 by pressing the pressing portion 54 forward. When the overlapping area of the first insertion hole 56A and the second insertion hole 57 is increased, the main body portion 51 and the clamp portion 52 can be moved relative to the string-like member 61, so that the string fastener 50 is moved to a desired position. It can be moved. When the pressing on the clamp portion 52 is stopped, the elastic force of the elastic portion 53 causes the clamp portion 52 to move in the opposite direction. Accordingly, the string-like member 61 can be fixed or held by the first insertion hole 56A of the main body 51 and the second insertion hole 57 of the clamp 52 in a sandwiching manner.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, It can change in the range which does not deviate from the objective of this invention, and the meaning.
